- Q: Home surveillance camera with which brand is good?
- A few meters of wireless home monitor is good. Through the mobile phone to achieve remote monitoring, the camera at home, mobile phone download APP, will be able to work, travel anywhere to monitor the situation at home.
- Q: Monitor camera resolution 752 * 582 is high HD it
- HD usually refers to 1280 * 720 (referred to as 720P) or 1920 * 1080 (referred to as 1080P). 752 * 582 is not high definition.
- Q: Monitor the camera, how much money one, the kind of video
- 20 meters of infrared one machine, domestic Sharp Rui tablets, between 180-300, SONY Rui film, between 200-400, which means that night vision can reach 20, if you are not demanding on the night, but the day See it, it is cheaper, Sharp Rui film 150, SONY Rui film 180. Give you a price, do not require the price of night vision.
- Q: Monitor the camera mentioned in the three stream, what is the meaning of ah, which three?
- Three streams can achieve local transmission and remote transmission of three different bandwidth required stream, the local transmission using high-bit stream can get higher HD video storage, remote transmission using a lower stream to adapt to CDMA / ADSL and other Network and get a higher image fluency.
- Q: How to monitor their own home in the home camera, in the first floor, in the 5th floor to see!
- Do not video, video cable directly connected to the TV on it. To video or to be connected to the computer, the computer must have the image acquisition card + software.
- Q: Monitoring the camera has a 700 line with 1080 lines of 900 lines is what does that mean? consult
- How many lines follow the concept of the simulation era, and how many lines can be resolved from left to right (similar to resolution, but not equal to resolution). 1080 refers to the video from top to bottom there are 1080 lines, also refers to the full HD resolution, and 1920 (each line) * 1080 (line), which is the format of digital video
- Q: Monitor the flash indicator on the DVR panel
- Are you buying a new hard drive? The hard disk must be formatted
- Q: 3.6mm and 6mm surveillance camera can see the screen angle is how much
- 3.6MM angle is generally about 87 degrees 6MM angle is 60 degrees. The scope of the monitoring is not the same, a clear distance is not the same, 3.6MM lens is generally the best clear distance of 7-8 m 6MM lens the best clear distance of 15 meters 3.6mm: 90 ° about 6mm: 60 ° 8mm: 45 ° about 12mm: 35 ° or so
- Q: Monitor the camera what is the zoom
- The lens is equivalent to the human eye lens, if there is no lens, the human eye can not see any objects; if there is no lens, then the camera output image is a vast expanse of white, no clear image output, which with our home camera and camera principle Is consistent. When the human eye can not stretch the lens to the normal position, that is, people often say myopia, the front of the scene becomes blurred; camera and lens with a similar phenomenon, when the image becomes unclear , You can adjust the camera's back focus, change the CCD chip and the lens reference plane distance (equivalent to adjust the position of the human eye lens), you can blur the image becomes clear. Thus, the role of the lens in the closed-circuit monitoring system is very important. Engineering designers and construction workers should often deal with the lens: the designer according to object distance, imaging size calculation lens focal length, the construction staff often on-site commissioning, part of the lens is to adjust to the best condition.
- Q: Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it
- CCD, English full name: Charge-coupled Device, the Chinese full name: charge-coupled components. Can be called CCD image sensor, also known as image controller. A CCD is a semiconductor device that converts an optical image into a digital signal. The tiny photoreceptor implanted on the CCD is called the pixel (Pixel). The higher the number of pixels on a CCD, the higher the picture resolution it provides. The CCD acts like a film, but it converts an optical signal into a charge signal. CCD has a number of neatly arranged photodiode, can sense the light, and the optical signal into electrical signals, the external sampling amplifier and analog conversion circuit into digital image signal.
